Paired electrolysis with 1,4-dimethoxybenzene (1) as a substrate was studied. Hydrogenation of the aromatic ring occurred to produce 1,4-cyclohexanedione (4) and two derivatives on Raney-nickel cathode. Two derivatives were converted into 4 by treatment of HCl aqueous solution. The total yield of 4 was 60% based on 1, whereas 4 was not formed on a platinum or lead cathode.
以 1,4-二甲氧基苯 (1) 为底物进行了配对电解研究。在雷尼-镍阴极上,芳香环发生氢化反应,生成 1,4-环己二酮(4)和两种衍生物。通过盐酸水溶液的处理,两种衍生物转化成了 4。在 1 的基础上,4 的总产率为 60%,而在铂或铅阴极上则不会生成 4。
